[swift-dev] Compiling Swift macOS 10.12.4 Xcode 9 beta 4

Thu Aug 10 10:07:10 CDT 2017

Hello everyone,

I followed the instructions on the Swift GitHub for installing and building Swift on my Mac but there is an error that I don't know how to fix (I am using the build-script -x command). Here is the error:

** BUILD FAILED **

The following build commands failed:
	PhaseScriptExecution CMake\ Rules /Users/trevorannedenise/swift-source/build/Xcode-DebugAssert/swift-macosx-x86_64/stdlib/public/SwiftRemoteMirror/Swift.build/Debug/swiftRemoteMirror-macosx.build/Script-340A90BA4E604C08A26364A6.sh
(1 failure)
utils/build-script: fatal error: command terminated with a non-zero exit status 65, aborting

There are also these errors a few lines before:
xcodebuild: error: SDK "/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.12.sdk" cannot be located.
codesign_allocate: error: unable to find utility "codesign_allocate", not a developer tool or in PATH
/Users/trevorannedenise/swift-source/build/Xcode-DebugAssert/swift-macosx-x86_64/Debug/lib/swift/macosx/libswiftRemoteMirror.dylib: the codesign_allocate helper tool cannot be found or used
make: *** [/Users/trevorannedenise/swift-source/build/Xcode-DebugAssert/swift-macosx-x86_64/Debug/lib/swift/macosx/libswiftRemoteMirror.dylib] Error 1
Command /bin/sh failed with exit code 2

I had forgot to do xcode-select, so I thought it was that but even as I selected the beta version of Xcode the error persists. What surprises me is that the utility searches for 10.12 SDK under Xcode.app which is Xcode 8 and not Xcode 9 even tough I did select Xcode 9 using xcode-select.

Do you have any idea of what is happening ?

Thank you

Trevör
